Ultra Beasts

These are the Ultra Beasts. 

And believe me, 

These Ultra Beasts were not legendary Pokémon

They were the Group of extra dimensional Pokémon originating from Ultra Space. 

All the Ultra Beasts were genderless. 

This is Nihilego that looked like a Jellyfish. 

But it's a Rock Poison Type Pokemon. 

This is Buzzwole. 

It looked like a huge anthropomorphic Mosquito with Pecs. 

But Buzzwole was one of the most powerful and the deadliest Ultra Beast of all Time. 

That's Pheramosa. 

Pheromosa looked like an anthropomorphic feminine Cockroach, 

but it looks skinny and slender. 

Pheromosa was one of the most beautiful Ultra Beast in the World. 

Buzzwole and Pheramosa are Bug Fighting Type Pokemon. 

That's Xurkitree. 

It looks tall but it resembles a vaguely Humanoid Mass of electrical Wiring. 

Xurkitree was an Electric Type Pokemon. 

This is Celesteela. 

A huge Humanoid Pokemon that is mainly green 

with bodily Construction that closely resembles 

that of a Bamboo Shoot. 

Celesteela has a Horn to drill. 

Celesteela was a Steel Flying Type Pokemon. 

That's Kartana. 

A small Humanoid Pokemon that looked like an Oragami. 

Kartana was a Grass Steel Type Pokemon. 

That's Guzzlord. 

A large dangerous Pokemon that devoured Mountains, Building, and anything else. 

Guzzlord was a Dark Dragon Type Pokemon and it was

one of the deadliest and the most voracious Ultra Beast in the World. 

That Must be Poipole. 

A small purple Pokemon  with a large head and small limbs, 

but it looked friendly. 

Poipole was a Poison Type Pokemon. 

That's definately a Naganadel. 

A Large purple Pokemon that has both draconic and insectoid features. 

Naganadel was a Poison Dragon Type Pokemon. 

That's Stakataka. 

This Pokemon looked like a walking Tower with Stones.  

Stakataka was a Rock Steel Type Pokemon. 

And that's Blacephalon.

A Pokemon that looked like a Clown. 

Blacephalon was a Fire Ghost Type Pokemon. 

A Codename for Nihilego was UB-01 Symbiont, 

A Codename for Buzzwole was UB-02 Absorption, 

A Codename for Pheramosa was UB-02 Beauty, 

A Codename for Xurkitree was UB-03 Lighting, 

A Codename for Celesteela was UB-04 Blaster, 

A Codename for Kartana was UB-04 Blade, 

A Codename for Guzzlord was UB-05 Glutton, 

A Codename for Poipole was UB Adhesive, 

A Codename for Naganadel was UB Stinger, 

A Codename for Stakataka was UB Assembly 

and a Codename for Blacephalon was UB Burst.  

The Ultra Beasts were from Pokemon Sun and Moon 
and Pokemon Ultra Sun and Ultra Moon.
I think Poipole, Naganadel, Stakataka and Blacephalon 
were not my least favorite Pokemon, 
but Nihilego, Buzzwole, Pheramosa, Guzzlord, Celesteela, Xurkitree, and Kartana 
were my least favorite Pokemon like Mewtwo.
